TO ALL WHOM IT MAY CONCERN:

Be it known that I, W. F. G. BEEUWKES, of Holland, in the county ofOttawa, and State of Michigan, have invented a new and Improved ChimneyTop or'Cap; and I do hereby declare that the following is a full,

clear, and exact description thereof, which will enable others skilledin the art to make and use the same,-

reference being had to the accompanying drawings, forming a partof thisspecification.

The present invention relates to a new and improved top or cap forchimneys of dwelling-houses, and other buildings, the principal objectbeing to prevent the roof of. the building, through which thechimneyextends, from becoming heated by the action of the heated currents ofair 'and products of combustion passing through the chimney, theimportance of which is obvious to all. I

In accompanying plate of drawings my improved chimney top or cap isillustrated, the figure being a central vertical section through thesamefishowing the chimney or escape pipe and a portion of the roof of abuilding.

A in the drawings represents a portion of the roof of a building, havingmy improved chimney top or cap applied to it; B the chimney or escapepipe passing up through the roof, but surrounded at such portion of itslength as passes through the roof by a concentric cylindrical casing, G,placed at a short distance therefrom,

and secured at its lower end to it by brackets, D, at suitable points,and at its upperend similarly attached to the inside of anotherand outerbut somewhat larger concentric casing or cylinder, F, fastened at itslower end to and around the opening G in the roof; which exterior casingF extends upwards nearly to the top of the chimney, with a covering orplate, H, over the spacer, between it and the chimney, thisplateprojecting beyond.

the casing F, with a short casing, J, attached to its under side,learing a space or chamber, K, between it and the exterior casing F. L acap-plate placed over the upper endof the chimney B, at a short distancetherefrom. M M a series of openings formed in the outer cylindricalcasing F, at or near its upper end, but above the end of the shortcasing J, placed around the'outside of the same at such end.

From the above-described arrangement and construction of my improvedchimney top, it is plain to be seen that, by surrounding the portionofthe chimney passing through the roof with the casing 'no heating ofthe roof from the action of the products'of combustion escaping throughthe chimney can possibly occur, thus preventing it from taking fire,while all heated air generated from the radiation of heat by the chimneyis free to escape from the chamber surrounding it through the aperturesM, in the upper portion of the-exterior casing 13, the cap-plate to thechimney and the cover to the casing F preventing snow or rain fromentering the same.

I'claim as new, and desire to secure by Letters Patent- The arrangementof theguard pipes or casings G and F, plate H, and short cylinder J forprotecting the roof from the heat'of the chimney, substantially asherein shown and described. 7 i
